HDP Sandbox 2.6 Automated Kerberos Installation and Configuration

sofianbenabdelh — Fri, 28 Jul 2017 15:07:09 GMT

Hello everyone there is my problem :

In order to automated kerberos installation i follow this tutorial for HDP sandbox 2.4 : https://community.hortonworks.com/articles/29203/automated-kerberos-installation-and-configuration.html

I already try to set up it manually but without success because of a connection problem with the kdc when i try to configure it on ambari web interface.

So i try the tutorial but now i have this problem when i launch it :

{

"status" : 400,

"message" : "java.lang.IllegalArgumentException: Invalid KDC administrator credentials.\nThe KDC administrator credentials must be set as a persisted or temporary credential resource.This may be done by issuing a POST (or PUT for updating) to the /api/v1/clusters/:clusterName/credentials/kdc.admin.credential API entry point with the following payload:\n{\n \"Credential\" : {\n \"principal\" : \"(PRINCIPAL)\", \"key\" : \"(PASSWORD)\", \"type\" : \"(persisted|temporary)\"}\n }\n}"

I try to solve the problem by fixing manually the credential but the script seems to modify (it changes my persisted credential by a temporary credential) it and i can't find where it do it (and also i don't know how to see the principal of the credential to understand maybe why it's not working).

I also want to specify that in 2.6 ambari's log are : user : raj_ops password : raj_ops I think i configure my ambari.props correctly :

CLUSTER_NAME=Sandbox AMBARI_ADMIN_USER=raj_ops AMBARI_ADMIN_PASSWORD=raj_ops AMBARI_HOST=localhost KDC_HOST=localhost REALM=EXAMPLE.COM KERBEROS_CLIENTS=localhost

I have no more ideas on how to solve the problem please help me ^^
